METHOD OF TREATING ROOFING MATERIAL,

Application filed July 12, 1923. Serial No. 651,097.

This invention relates to a method for by the arrow 6. This eii'ects a sharp lateral treating roofing material such as asphalt bend of the ends of the material upwardly of shingles, strips and roll goods, preparatory the general plane of the roofing piece when to applying plastic material thereto after laid as shown at 7 in Figures 2, 3 and 4, which 5 they have been laid on the roof. acts to hold the plastic material, which may 55 By the application of such plastic material be brushed or troweled thereon after it is artistic effects may be produced both by ap laid, in position on the roof until such plastic plying colors, and by mechanical treatment becomes set or hardened. By acting on sevof the plastic, one method of accomplishing eral superposed pieces of the roofing between the latter result being to run a trowel along the clamping plates simultaneously uniform- 60 the butt ends of the courses, forming outity in the final result is easier to obtain than standing ridges thereon which inereasethe if single ones only are so treated and a great apparent thickness of the materialof the saving in time is also effected. courses, as more fully described and claimed Having thus described this invention it in my application for patent filed May 5, should be evident to those skilled in the art 65 1923, Serial No. 636,853 whiclr-hasbecome that various changes and modifications may Patent No. 1,673,991 for roofing and method be made therein without departing from its of laying the sa-me. spirit or scope as defined by the appended According to the present invention, therecla1ms. v fore, these butt ends of the shingle material I claim: w 70 are bent outwardly sharply from the plane of 1. The method which comprises clamping a the remainder of each 'unit, immediately back roofing element leaving marginal portions from their edges to aid in retaining these unconfined and then applying pressure laterridges of plastic material. One method of ally and inwardly against sald portions to accomplishing this is disclosed in the accombend them laterally of the plane of the re- 75 panying drawings in which mainder of the material and upwardly of the Figure 1 is a somewhat diagrammatic side general plane of the element when laid. elevation of a press showing a bundle of 2.
